[gdal-dev] ZMAP driver, support for comment section "+"

Olivier Chatry
Hello !

I have a ZMAP file that apparently have comment inside, after the @ ( start of the grid definition). 

Here is an extract :


!     bla bla
!     bla bla
!     GRID FILE NAME   : bla bla
!     CREATION DATE    : bla bla
!     CREATION TIME    : bla bla
@blabla.zmap HEADER                     ,      GRID, 5
      15,    -99999.0000,       ,      4,      1
     441,    561,    867000.0000,    481000.0000,   9562000.0000,   2573000.0000
         0.0000,         0.0000,         0.0000
@
+ Grid data starts after this line
    -99999.0000    -99999.0000    -99999.0000    -99999.0000    -99999.0000

QGIS was able to load the file just fine. I was not able to find any standard for the ZMAP format ( but did not look a lot for it ).

I would gladly make a patch, but I'm not sure how I should proceed.

Any help ?

Hi,

Have you already found http://www.gdal.org/frmt_various.html and a link to
informal specification
https://lists.osgeo.org/pipermail/gdal-dev/2011-June/029173.html and the
code of the driver at
https://trac.osgeo.org/gdal/browser/trunk/gdal/frmts/zmap?
